Titanium alloys have been widely used for more than fifty years in orthopedic and dental areas. The objective of this work was to predict, prepare, characterize and analyze the influence of some thermomechanical treatments on the structure, microstructure, and some selected mechanical properties of Ti-10Mo-Mn alloys. The samples were cast, homogenized, and hot-rolled. After each processing step, XRD, OM, and SEM measurements were performed to analyze the structure and microstructure. For the mechanical properties, Vickers microhardness and elastic modulus measurements were obtained. The equivalent molybdenum analysis predicted that the alloys would present only the β phase, which was confirmed with the structural and microstructural characterization. Regarding the mechanical properties, the hardness remained high and the elastic modulus below the alloys already commercially used as biomaterials. The modulus values decreased compared to cp-Ti by adding alloying elements (Mo and Mn are β-stabilizing agents). (Financial Support: Capes, CNPq and FAPESP).
